프로파일 나선형 합성수지관 코팅 직관 파이프{Cotting Pipe}Profile Spiral Synthetic Resin Pipe Coated Straight Pipe {Cotting Pipe}

본 발명은 합성수지관 코팅 직관 파이프에 관한 것으로 프로파일 프로파일 나선형 접합관의 표면에 원통형 다이스를 통하여 용융수지를 압출하여 새로운 코팅층을 형성하여 파이프의 외부가 평활하고 매끄러운 직관이 되며 전체적인 파이프의 강성과 강도를 증대시킴은 물론 시공작업이 간편하게 이루어지게 하고 사용 도중 제품이 파손되거나 누수되는 것을 방지하며 외관이 직관 형태로 취할수 있도록 한 프로파일 나선형 합성수지관 코팅 직관 파이프에 관한것이다.The present invention relates to a straight pipe pipe coated with a synthetic resin pipe, to form a new coating layer by extruding a molten resin through a cylindrical die on the surface of a profile profile spiral joint pipe to form a smooth and smooth straight pipe outside and to improve the overall rigidity and strength of the pipe. The present invention relates to a profile spiral synthetic pipe coated straight pipe that allows for increased construction, ease of construction, and prevents product from being damaged or leaked during use, and allows the appearance to be taken in the form of a straight pipe.

일반적으로 오,폐수관 또는 하수관으로 사용되는 관은 콘크리트관 금속관으로 이루어져 있다. 이러한 관은 중량이기 때문에 운반과 취급이 불편하고 설치작업이 어려운 단점이 있으며, 이를 장기간 사용할 경우 관 자체가 부식되는 관계로 수시로 관을 교체 하여야 하는 제반 문제점이 있었다.Generally, the pipes used as sewage, wastewater pipes or sewage pipes are made of concrete pipes and metal pipes. Such a pipe has a disadvantage in that it is inconvenient to transport and handle and difficult to install due to its weight, and when it is used for a long time, the pipe itself is corroded and there is a problem that the tube must be replaced at any time.

따라서 종래에는 상기와 같은 단점을 감안하여 내구성, 내마모성을 충족하는 합성수지재의 프로파일 나선형 합성수지관이 안출된 바 있다.Therefore, in the related art, a profile spiral synthetic resin tube of a synthetic resin material that satisfies durability and wear resistance has been devised in view of the above disadvantages.

이의 구성을 간단하게 살펴보면 프로파일 나선형 합성수지관은 단면이 사각형이나 원형의 형태를 취하는 프로파일을 압출다이를 이용하여 연속 압출 성형한후, 압출된 프로파일을 나선성형 드럼에 나선형으로 감고, 나선형으로 감겨진 프로파일과 프로파일 사이에 형성된 틈새에 수지를 공급하여 이를 일체로 연결 접합함으로써 원통형의 관 형태로 제작 사용하고 있다.In brief, the configuration of the profile spiral synthetic resin tube is formed by continuously extruding a profile having a square or circular cross section using an extrusion die, and then spirally wound the extruded profile on a spiral drum and spirally wound the profile. It is produced and used in the form of a cylindrical tube by supplying resin to the gap formed between the profile and the profile and connecting them integrally.

상기한 프로파일 나선형 합성수지관은 압출성형시 나선형의 틈새에 수지를 공급하여 서로 접합하고 있기 때문에 장기간 사용시 접합 부분이 산화되어 프로파일 서로 분리되는 현상이 발생하여 수명이 단축되는 단점이 있으며 표면에 올록볼록한 나선형의 홈이 연속하여 나있어 하수관 파이프에 있어서 가장 핵심이라 할 수 있는 기밀성이 현저하게 저하될 뿐만아니라 시공이 매우 까다롭고 불편한 단점이 발생되었다.Since the profile spiral synthetic resin tube is connected to each other by supplying resin to the gap of the spiral during extrusion molding, the joint part is oxidized and the profile is separated from each other when it is used for a long time, which shortens the lifespan and convex spiral on the surface. Since the grooves of the sequential grooves are not only markedly deteriorated in the airtightness of the sewage pipe, but also very difficult and inconvenient construction.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 종래의 프로파일 나선형 합성수지관의 표면에 원통형의 다이스를 통하여 용융수지를 압출하여 파이프의 외부에 덧씌우고 이를 진공냉각시켜서 새로운 코팅층을 형성하여 파이프의 외부가 평활하고 매끄러운 직관이되며 전체적인 파이프의 강성과 강도를 증대시킴은 물론 시공작업이 간편하게 이루어지게 하고 사용도중 제품이 파손되거나 누수되는 것을 방지하며 외관이 직관 형태로 취할 수 있도록한 프로파일 나선형관 코팅 직관 파이프를 제공하는데 있다.Accordingly, an object of the present invention is to conceive in view of the conventional problems as described above, a new coating layer by extruding the molten resin through the cylindrical die on the surface of the conventional profile spiral synthetic resin pipe and covered with the outside of the pipe and vacuum cooled it To make the outside of pipes smooth and smooth, increase the overall rigidity and strength of the pipes, make construction easier, and prevent the product from being damaged or leaked while in use. One profile spiral tube coated straight pipe.

상기와 같은 목적을 달성하기 위한 수단으로 본 발명은 오,폐수관 또는 하수관에 사용되는 파이프에 있어서 상기파이프는 사각이나 원형 프로파일이 일정한 간격을 두고 배열형성되며 프로파일과 프로파일의 접촉부분에 접합수지가 투입되어 원통형상의 프로파일 나선형 합성수지관이 형성되게하고, 이 파이프의 외부에 다시 새로운 원통형의 수지층을 형성 시켜서 일체형 의 코팅 직관 파이프가 되는 것을 기술적 구성상의 기본 특징으로 한다.As a means for achieving the above object, the present invention is a pipe used for sewage, sewage pipe or sewage pipe, the pipe is formed in a square or circular profile is arranged at regular intervals and the joint resin is connected to the contact portion of the profile It is a basic feature of the technical construction that it is injected into a cylindrical profile spiral synthetic resin tube, and a new cylindrical resin layer is formed outside the pipe to form an integral coated straight pipe.

이하 본 발명의 바람직한 실시예를 첨부도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도4는 본 발명에 따른 프로파일 나선형 합성수지관 코팅 직관파이프 단면도이다.Figure 4 is a cross-sectional view of the profile spiral synthetic resin tube coated straight pipe according to the present invention.

본 발명에 따른 프로파일 나선형 합성수지관 코팅 직관 파이프(10)는 크게 내부에 합성수지재 다각형의 프로파일(20) 과 그 프로파일(20)과 프로파일(20) 사이에 접합수지에 의한 접합층(30) 형성되고 일정한 간격을 가지고 연속하여 접합되어 다수 배열된다.Profile spiral synthetic resin pipe coated straight pipe 10 according to the present invention is largely formed inside the profile 20 of the synthetic resin polygon and the bonding layer 30 by the joint resin between the profile 20 and the profile 20 A plurality of contiguous are arranged in series at regular intervals.

외부 코팅층(40)은 내부에 프로파일 합성수지관의 외부에 덧씌워져서 형성되는데 원통으로 덧씌워져서 내층프로파일 합성수지관(50)의 올록볼록한 나선형상을 채워서 매끈한 외부를 갖는 일체형의 직관 형상이 된다.The outer coating layer 40 is formed by overlaying the outside of the profile synthetic resin tube therein is covered with a cylinder to fill the convex helical shape of the inner layer profile synthetic resin tube 50 to have an integral straight tube shape having a smooth outside.

한편 상기한 외부코팅층(40)의 강성과 강도를 부여하여 전체적인 파이프의 강성을 증대시키기 위한 수단으로 합성수지 원료에 화이버(유리섬유)같은 보강재를 중량비 0∼50％ 혼합 용융하여 원료로 도 사용할수있다.Meanwhile, as a means for increasing the overall pipe stiffness by providing the stiffness and strength of the outer coating layer 40, a reinforcing material such as fiber (glass fiber) may be mixed and melted in a weight ratio of 0 to 50% to be used as a raw material. .

이와같이 화이버 성분을 혼합용융하여 외부코팅층(40)을 형성하였을 때 강도가 보다 향상된 파이프를 얻을수 있었다.In this way, when the fiber component was mixed and melted to form the outer coating layer 40, a pipe having improved strength was obtained.

상기와 같은 프로파일 나선형 합성수지관 코팅 직관 파이프를 압출성형하기 위한 성형 장치를 살펴보면 본 발명은 도5에서와 같이 합성수지 프로파일(20)이 공급되면 공급된 합성수지 프로파일(20)을 사용하여 프로파일 나선형 합성수지관을 제조하는 프로파일 나선형 합성수지관 제조장치(200)이 형성되고 후단에는 회전 코팅원통다이스(300)가 설치되어 다이스가 같이 회전하면서 원통형상으로 동시 압출되어 코팅층을 형성하게 되고 후단에는 회전진공수단(400)이 설치되어 같이 회전하면서 파이프를 진공 냉각하여 직관으로 성형 시켜준다. 또한 후단에는 커팅수단(500)이 구비되어 성형된 제품을 일정규격의 크기로 절단하여 제품화 한다.Looking at the molding apparatus for extruding the profile spiral synthetic pipe coated straight pipe as described above, the present invention is a synthetic spiral profile using the supplied synthetic resin profile 20 when the synthetic resin profile 20 is supplied as shown in FIG. Spiral synthetic resin pipe manufacturing apparatus 200 to be produced is formed and the rotary coating cylindrical dice 300 is installed at the rear end is rotated together to simultaneously extrude in a cylindrical shape to form a coating layer and the rotary vacuum means 400 at the rear end It is installed and rotates together to cool the pipe to form a straight pipe. In addition, the rear end is provided with a cutting means 500 is formed into a product by cutting the molded product to a certain size.

좀더 자세하게는 합성수지 프로파일(20)이 프로파일 합성수지관 제조장치(200)에 공급되면 성형드럼 회전모터(201)의 구동으로 기어박스(202)에 전달된 동력이 다시 회전드럼(203)을 회전 구동하게 되어 합성수지 프로파일(20)을 회전드럼에 연속하여 감게된다.In more detail, when the synthetic resin profile 20 is supplied to the profile synthetic resin tube manufacturing apparatus 200, the power transmitted to the gearbox 202 by the driving of the molding drum rotating motor 201 causes the rotating drum 203 to rotate again. The resin profile 20 is then wound on the rotating drum continuously.

회전드럼의 외주면에 감겨진 합성수지 프로파일(20) 틈새에는 접합용융수지노즐(204)이 나선관의 간극 내면에 용융된 합성수지를 주입한다.In the gap of the synthetic resin profile 20 wound on the outer circumferential surface of the rotating drum, the molten synthetic resin nozzle 204 injects the molten synthetic resin into the gap inner surface of the spiral tube.

나선관의 간극에 합성수지가 주입되면 압착롤러(205)가 합성수지 접합층(30)을 상하방향으로 압착하여 나선관을 상호 접합시키게 된다. 접합된 프로파일 나선형 합성수지관은 회전드럼(203)에 의해 앞쪽으로 전진하게 된다.When synthetic resin is injected into the gap of the spiral tube, the compression roller 205 compresses the synthetic resin bonding layer 30 in the vertical direction to bond the spiral tubes to each other. The bonded profile helical synthetic resin tube is advanced forward by the rotating drum 203.

전진된 파이프는 회전코팅다이스(300)의 원통내부를 통과하게 되는데 회전 코팅다이스(300)은 압출기로부터 용융수지를 유로(301)를 통하여 회전코팅다이스(300)내부로 투입되고 회전코팅다이스(300) 내부로 투입된 원료는 원통성형공간(303)으로 용융상태로 동시압출파이프와 같은 속도로 다이스가 회전하면서 파이프의 외주변에 접착되어 외부코팅층(40)을 형성한다.The advanced pipe passes through the inner cylinder of the rotary coating die 300, the rotary coating die 300 is introduced into the rotary coating die 300 through the flow path 301 from the extruder and the rotary coating die 300 ) The raw material introduced into the cylindrical molding space 303 is bonded to the outer periphery of the pipe while the die rotates at the same speed as the coextrusion pipe in the molten state to form the outer coating layer 40.

후단에는 회전진공수단(400)이 구비되어 파이프의 외주면에 접착된 용융수지를 파이프 회전속도와 같은 속도로 회전진공드럼(401)이 회전하면서 진공냉각시켜서 외부코팅층이 매끈한 직관인 외부코팅층(40)을 갖는다.At the rear end, the rotary vacuum means 400 is provided, and the melted resin adhered to the outer circumferential surface of the pipe is vacuum-cooled while the rotary vacuum drum 401 rotates at the same speed as the pipe rotation speed, so that the outer coating layer is a smooth straight outer coating layer 40. Has

이렇게 만들어진 프로파일 나선형 합성수지관 코팅 직관 파이프(10)는 커팅수단(500)에 의해 일정한 길이로 절단되어 완성된 성형물이 만들어진다.The profile spiral synthetic resin pipe coated straight pipe 10 thus made is cut to a certain length by the cutting means 500 to form a finished molding.

상기와 같이 만들어진 파이프는 나선형 접합관의 외부표면에 코팅층으로 보강하여 만들어진 외부직관으로 외력 및 내력에 대해서도 충분한 강도를 갖는 잇점이 있고, 시공 작업이 간편하게 이루어지게 하고 사용도중 제품이 파손되거나 누수되는 것을 방지하여 외부가 직관 형태를 취할수 있는 파이프를 얻을수 있는 등의 효과가 있는 것이다.The pipe made as described above is an external straight pipe made by reinforcing the outer surface of the spiral joint pipe with a coating layer, which has the advantage of sufficient strength against external force and strength, and makes the construction work simple and prevents the product from being damaged or leaked during use. This prevents the pipes from getting outside and having a straight pipe shape.
